Answer
Rectangular coordinates: $(0,0)$
-------------------------------
Work Step by Step
In polar coordinates, the first number represents the value for $r$, and the second number represents the value for $\theta$.
$(0, -\frac{7\pi} 6)$
Thus: $r = 0$ and $\theta = - \frac {7\pi} 6$
Knowing that $x = rcos(\theta)$ and $y = rsin(\theta):$
$x = rcos(\theta) = (0)(cos(-\frac{7\pi} 6)) = 0$
$y = rsin(\theta) = (0)(sin(-\frac{7\pi} 6)) = 0$
